Recent studies have demonstrated that patients with throat-related reflux often require twice daily proton pump inhibitor therapy to attain significant symptomatic improvement, with once daily therapy offering little relief. As dexlansoprazole is a twice-daily release proton pump inhibitor requiring only once-daily dosing, it may provide LPR symptomatic relief comparable to that of twice daily dosing, yet be more readily approved by third party payers because of its once daily dosing requirements. It is hypothesized that, in patients with pharyngeal-probe proven throat reflux, there will be significantly greater improvement in symptoms and pharyngeal probe findings in those patients receiving dexlansoprazole than those receiving placebo alone.
